JAMES HAWORTH, OF FRANKFORD, PENNSYLVANIA.

LOOlVL Specificaton of Letters Patent No. 5,021, ated March 20, 1847.

To all whom it may concem: p

Be it known that I, JAMEs HAWORTH, of Frankford, in the county ofPhiladelphia. and State of Pennsylvania, have invent-ed a new and usefulImprovement in Looms, which is described as follows, reference being hadto the annexed drawing of the same, making part of this specification..

Figure 1 is a plan or top view ofVV the frame and lathe.

In the construction of a common loom wherein a spring is used to forcethe swelllever against the shuttle ,considerable inconvenience isexperienced arising from the friction of the shuttle in leaving the box.

against the swell lever pressed against it by the usual spring.

My improvement is designed to remove said fricton of the shuttle againstthe swell-lever and thereby to reduce the power required to operate theloom.

Besides the aforesaid object I also by my improvement effect anotherimportant object, name1y running the loom backward or in a contrarydirection without the use of' the shuttle-when the loomis not performingthe operation of weaving. .v

These two objects I effect in the following described manner I secure tothe stop rod of the loom an additional finger A which is to be connectedloosely With the arm B of the lathe by' means of a pin C inserted intothe arm; or by bending thev finger A so as to lie upon the arm B; or

-lever H.

otherwise connected by which connection the stop-rod D. is vibratedduring the operation of the loom in weaving, said vibration of the'stop-rod having the effect of relieving the pressure of the finger E ofthe said stop rod against the swell lever F which bears against theshutt1e, thus relieving the shuttle. When the loom is not performing theoperationof weaving but is running in a contrary direct-ion then thesaid ,addit-ional finger A vibrates the stop rod D causing the stopfinger G to clear the stop This last named effect enables the weav'er torun the loom backwardv for any required purpose Without the necessity ofholding back the swell lever by his hand or otherwise.

VhatIV claim as my invention anddesire to secure by Letters Patent is-The mode of relieving the pressure of the f* swell lever F against theshuttle Whilst the shuttle is leaving the bo-X also the mode of causingthe loom to run back- -Ward without the use of the shuttle by means ofthe before described combination,
